The probabilities are:

1. P(yellow) = 2/5

2. P(red) = 3/10

3. P(blue) = 3/10

4. P(blue or yellow) = 7/10

5. P(red or blue) = 3/5

To find the probability that a person in each color seat would receive the free tickets, we need to calculate the probabilities of each event.

1. P(yellow): There are 8 yellow seats out of a total of 20 seats in Section A. Therefore, the probability of selecting a yellow seat at random is P(yellow) = 8/20 = 2/5.

2. P(red): There are 6 red seats out of a total of 20 seats in Section A. Therefore, the probability of selecting a red seat at random is P(red) = 6/20 = 3/10.

3. P(blue): There are 6 blue seats out of a total of 20 seats in Section A. Therefore, the probability of selecting a blue seat at random is P(blue) = 6/20 = 3/10.

4. P(blue or yellow): To calculate the probability of selecting a blue or yellow seat, we add the individual probabilities of selecting a blue seat and a yellow seat: P(blue or yellow) = P(blue) + P(yellow) = 3/10 + 2/5 = 7/10.

5. P(red or blue): To calculate the probability of selecting a red or blue seat, we add the individual probabilities of selecting a red seat and a blue seat: P(red or blue) = P(red) + P(blue) = 3/10 + 3/10 = 6/10 = 3/5.

Answer:

See below

Step-by-step explanation:

Starting with 42, there would be two branches of 2 and 21 connected to 42. Since 2 is prime, there are no more branches. Since 21 is composite, then two more branches are drawn of 3 and 7 connected to 21. Since 3 and 7 are prime, there are no more branches.

Therefore, the prime factorization of 42 is 2*3*7, and its factors would be 1,2,3,6,7,14,21,42.

Answer:

Step-by-step explanation:

You want the values of x and z in the figure where one pair of parallel lines crosses another.

Where a transversal crosses parallel lines, corresponding angles are congruent. This gives rise to several other relationships, each with its own name. The net result is that all acute angles are congruent, and all obtuse angles are congruent. The acute and obtuse angles are supplementary. (If the crossing is at right angles, then all angles are congruent.)

Here, the angle marked x° is supplementary to the one marked 77°:

  x = 180 -77 = 103

The angle marked (3z -19)° is congruent to the one marked 77°:

  3z -19 = 77

  3z = 96 . . . . . . add 19

  z = 32 . . . . . . . divide by 3

The value of x is 103; the value of z is 32.

__

Additional comment

The various pairs of angles at a transversal can be described as "consecutive", "alternate", "interior", "exterior", "same-side". Of course, where lines cross, the angles can also be "vertical" or "opposite" or "adjacent" or a "linear pair."

Depending on the relationship, the angles will be congruent or supplementary. For example, "alternate exterior angles" are congruent; "consecutive interior angles" are supplementary.

(f/g)(-5) is equal to 1/4, and the value -1 is not in the domain of f/g.

To find (f/g)(-5), we need to substitute -5 into the functions f(x) and g(x) and then divide f(-5) by g(-5).

Given:

f(x) = (4+x)(6+x)

g(x) = 1+x

Substituting -5 into the functions:

f(-5) = (4+(-5))(6+(-5)) = (-1)(1) = -1

g(-5) = 1+(-5) = -4

Now, we can calculate (f/g)(-5):

(f/g)(-5) = f(-5) / g(-5) = -1 / -4 = 1/4

Therefore, (f/g)(-5) equals 1/4.

Now let's determine the values that are not in the domain of f/g. The values that are not in the domain of f/g are the values that make the denominator g(x) equal to zero. In this case, the denominator is g(x) = 1+x.

To find the values that make the denominator zero, we solve the equation:

1 + x = 0

Subtracting 1 from both sides, we get:

x = -1

So, the value x = -1 is not in the domain of f/g because it would make the denominator equal to zero.

From the diagram, C is the midpoint of AB.

Now,

AC = CB (As C is the midpoint of AB)

Assuming the length of AB is 32 and the length of AC is +10, we can find the length of CB by subtracting the length of AC from the length of AB.

The probability that one of the books selected is a mathematics book and the other two are either physics or history books can be calculated as follows:

1. Calculate the total number of possible combinations of selecting 3 books out of the given options. Since there are 3 mathematics books, 3 physics books, and 1 history book, the total number of combinations is:

  Total Combinations = C(3,1) * C(3,2) = 3 * 3 = 9, where C(n,r) represents the number of combinations of selecting r items from a set of n items.

2. Calculate the number of favorable combinations where one book is mathematics and the other two are either physics or history books. There are 3 ways to select one mathematics book and 3 ways to select two books from the remaining 6 (3 physics + 1 history) books. Therefore, the number of favorable combinations is:

  Favorable Combinations = C(3,1) * C(6,2) = 3 * 15 = 45.

3. Calculate the probability by dividing the number of favorable combinations by the total number of combinations:

  Probability = Favorable Combinations / Total Combinations = 45 / 9 = 5/1 = 5.

Therefore, the probability that one of the books selected is a mathematics book and the other two are either physics or history books is 5/9 or approximately 0.5555.

The sum of the infinite geometric series representing the population of the local species of flies is given by the sigma notation ∑ (from n = 1 to ∞) 940 * (1/5)^(n-1). The series converges, and the sum, which represents the upper limit of the population, is 1175.

To write the sum in sigma notation, let's break down the given information step by step:

The first term of the infinite geometric series is a1 = 940.

The common ratio (r) is one fifth (1/5), which means each term is obtained by multiplying the previous term by 1/5.

In sigma notation, the sum of an infinite geometric series can be expressed as follows:

∑ (from n = 1 to ∞) a1 * r^(n-1)

In this case, the first term a1 is 940, and the common ratio r is 1/5. Therefore, the sigma notation for the sum of this series is:

∑ (from n = 1 to ∞) 940 * (1/5)^(n-1)

To calculate the upper limit of this population, we need to find the sum of the series. However, to determine if the sum is possible, we can check if the series converges or diverges.

For a geometric series to converge, the absolute value of the common ratio (|r|) must be less than 1. In this case, |1/5| = 1/5, which is less than 1. Therefore, the series converges.

The sum of an infinite convergent geometric series can be calculated using the formula:

S = a1 / (1 - r)

In our case, a1 = 940 and r = 1/5. Substituting these values into the formula, we can calculate the sum:

S = 940 / (1 - 1/5)

S = 940 / (4/5)

S = 940 * (5/4)

S = 1175

So, the upper limit of the population is 1175.

The equation that best represents the relationship between x and y is:

y = -1/2x + 11

To determine the equation that best represents the relationship between the quantities x and y, we can examine the pattern in the table.

Looking at the x-values and their corresponding y-values, we can observe that as x increases by 2 units, y decreases by 1 unit.

Using this pattern, we can find the equation that represents the relationship.

When x = 2, y = 10

When x = 4, y = 9

When x = 6, y = 8

When x = 8, y = 7

Based on the pattern, we can see that y decreases by 1 unit for every 2 units increase in x.

Therefore, the equation that best represents the relationship is:

y = -1/2x + b

To find the value of b (the y-intercept), we can substitute the values of x and y from any point in the table. Let's use the first point (x = 2, y = 10):

10 = -1/2(2) + b

10 = -1 + b

b = 11

So the equation that best represents the relationship between x and y is:

y = -1/2x + 11

Therefore, the correct answer is: y = -1/2x + 11.

Step-by-step explanation:

In order to find the distance that Anna has travelled, we can derive the formula from the speed formula which is:

where v is speed, s is distance and t is time. So by solving for distance (s), we have:

[tex]\displaystyle{s=vt}[/tex]

Apply the distance travelled formula, we know that speed (v) = 40 km/h and time (t) = 1.5 hours. Thus,

[tex]\displaystyle{s=40 \ \text{km/h} \cdot 1.5 \text{h}}\\\\\displaystyle{s=60\ \text{km}}[/tex]

g(x) = -2√x + 8 is the function that has the same range as f(x) = -2√(x - 3) + 8. Both functions have the range of y ≤ 8

The function that has the same range as f(x) = -2√(x - 3) + 8 is g(x) = -2√x + 8. Both functions have the range of y ≤ 8.There are a few steps involved in determining which function has the same range as f(x) = -2√(x - 3) + 8. The range of a function refers to all the possible output values that the function can produce.Let's begin by examining the original function:f(x) = -2√(x - 3) + 8The square root symbol (√) implies that x-3 must be greater than or equal to 0. If x-3 is negative, then the function would produce an imaginary result.

Let's solve for x when f(x) = 0:0 = -2√(x - 3) + 8-8 = -2√(x - 3)4 = √(x - 3)16 = x - 3x = 19This tells us that the x-value that produces an output of 0 is x = 19. To determine the range, we need to find the maximum and minimum output values. We can use a graphing calculator or sketch a graph to determine the shape of the function and the range.The shape of the function suggests that the range is y ≤ 8, which means that the maximum value of the function is 8. This tells us that any function with the same maximum output value of 8 will have the same range as f(x).

Answer:

C = 18.2 in.

Step-by-step explanation:

Step 1:  Find the diameter of the circle:

The normal formula for the circumference of a formula is given by:

C = πd, where

We're given the radius, r, and since the diameter is simply twice the radius, we can find the diameter by multiplying 2.9 by 2:

d = 2r

d = 2(2.9)

d = 5.8

Thus, the diameter is 5.8 in.

Step 2:  Find the circumference, C (rounded to the nearest tenth), by plugging in 5.8 for d and 3.14 for π in the circumference formula:

C = 3.14(5.8)

C = 18.212

C = 18.2

Thus, the circumference of the circle is about 18.2 in.

Based on the calculations, option D, which is $5,000 at 2 percent interest compounded for four years, will result in the least amount of interest paid.

To determine which loan will result in the least amount of interest paid, we need to calculate the total interest for each option and compare them. Let's calculate the interest for each loan:

A. $10,000 at 2 percent interest compounded for four years:

To calculate the compound interest, we use the formula A = P(1 + r/n)^(nt), where A is the future value, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

For option A, the future value (A) can be calculated as:

A = 10,000(1 + 0.02/1)^(1*4) ≈ 10,816.65

The interest paid would be the difference between the future value and the principal:

Interest = 10,816.65 - 10,000 = 816.65

B. $10,000 at 2 percent simple interest for four years:

For simple interest, we use the formula I = P * r * t, where I is the interest, P is the principal amount, r is the interest rate, and t is the number of years.

For option B:

Interest = 10,000 * 0.02 * 4 = 800

C. $5,000 at 4 percent interest compounded for four years:

Using the compound interest formula:

A = 5,000(1 + 0.04/1)^(1*4) ≈ 5,897.77

Interest = 5,897.77 - 5,000 = 897.77

D. $5,000 at 2 percent interest compounded for four years:

Using the compound interest formula:

A = 5,000(1 + 0.02/1)^(1*4) ≈ 5,407.10

Interest = 5,407.10 - 5,000 = 407.10

Comparing the total interest paid for each option:

A: $816.65

B: $800

C: $897.77

D: $407.10
